Abstract (en)

A synthesis lighting environment representation of a 3D scene is constructed by: - receiving (10) data representative of at least one first image of the 3D scene taken from at least one location outside the 3D scene; - receiving (20) data representative at least one second image of the 3D scene taken from at least one filming position inside the 3D scene; - merging (30) a first lighting environment representation derived from the data representative of the first image(s) and a second lighting environment representation derived from the data representative of the second image(s) into the synthesis lighting environment representation (Rep).
